the macroalgae in the fuge feeds on the nutrients, which is made by fish waste etc. so if you have fish in the tank, you have to feed them, right? feeding them the algae from the fuge is not going to produce anymore waste than feeding them flake food. it's a cycle. the algae in the fuge is to keep phosphates, etc in the tank at reasonable levels, feeding the fish is not going to throw the levels into the stratosphere.
